Investigation of Ethernet switches behavior in presence of contending flows at very high-speed

Abstract : This paper examines the interactions between layer 2 (Ethernet) switches andTCP in high bandwidth delay product networks. First, the behavior of a rangeof Ethernet switches when two long lived connections compete for the sameoutput port is investigated. Then, the report explores the impact of these behaviorson TCP protocol in long and fast networks (LFNs). Several conditions inwhich scheduling mechanisms introduce heavy unfair bandwidth sharing andloss burst which impact TCP performance are shown.
